Tesla Powerwall is a product line of rechargeable lithium-ion home energy storage manufactured by Tesla Energy, a division of Tesla. Its purpose is to store backup power, allow the owner to use an alternative source of energy during peak hours, or otherwise for self-consumption.

Consumer impact summary

  • Requires app download: To have full use of functionality and features, the customer must download the Tesla application.
  • Always online: The product itself does not require internet connectivity per se, but certain features will not be available. More notably, it is stated in the limited warranty agreement that failure to register and connect to the internet will greatly decrease the duration of the warranty.[2] This effectively "encourages" the customer to always be connected so that Tesla Energy can remotely push firmware updates.
  • Market control: Since Tesla Energy does not provide official numbers, it is difficult to determine the Powerwall's popularity in the home energy storage market.

Incidents

This is a list of all consumer-protection incidents related to this product line. Any incidents not mentioned here can be found in the Tesla Powerwall category.

Powerwall 2 recall and lawsuit (2025—)

Main article: Tesla remotely discharges and disables recalled Powerwall 2 units

On 16 September 2025, the Australia Competition and Consumer Commission published a notice that Tesla was recalling affected Powerwall 2 units due to "certain lithium-ion battery cells from a third-party supplier in a subset of Powerwall 2 systems that may fail and overheat".[4][5]

A recall was issued nearly two months later, on 13 November 2025, by the United States Consumer Product Safety Commission due to the same concerns.[6]

In both cases, Tesla had also pushed a remote update to affected Powerwall 2 owners that limited or drained the batteries and disabled its ability to recharge.[7]

A class-action lawsuit was filed 26 November 2025 in Florida by Arthur Brown, an owner of a Tesla Powerwall 2 unit.[8]
